The shock jock garnered plenty of headlines during his time on the reality TV show after revealing details of the longstanding feud with his former 2UE colleague.

After hearing the story, Laws didn't mince words when prompted during an interview with Fitzy and Wippa to send a message to Price in the jungle: "Hey Steve, if you happen to be listening: go f**k yourself."

Now, Price has hit back, telling the Nova breakfast show the "fake-haired" Laws should just retire.

"He's got a great voice but he's got Brillo [steel wool] for hair," the 62-year-old said bitingly.

"Mate, disappear - you're a legend ... but give it away, you've had your time in the sun."

During his time on I'm A Celeb, Price claimed the pair had first had a huge blow-up over Laws' '50 Years on Radio' commemorations.

"We had to say what we thought of John. What always struck me about John Laws is that he has very weird hair, looks like it's green and fake. Next day I am sat in my office and he gets off air and comes in. 'You bleep-bleep-bleep! You ever do that to me again and I'll bleep smash you!'" Price recalled.

Price was off the show last night, leaving Casey Donovan, Natalie Bassingthwaighte, Nazeem Hussain and Dane Swan as the final four of the season, with one to win $100,000 for the charity of their choice.

"People I think invested in the show know that it is hard, but until you are actually in there you don't realise that this is all very real," he said.

"There is no pretend there, you don't duck out the back and have a cold beer or a hamburger. I have absolutely no doubt this show has put 10 years on my life, health-wise there is no doubt."
